Gabbatha - Gab Baitha, i.e., "the ridge of the house" = "the temple-mound," on a part of which the fortress of Antonia was built. This "temple-mound" was covered with a tesselated "pavement" (Gr. lithostroton, i.e., "stone-paved"). A judgement-seat (bema) was placed on this "pavement" outside the hall of the "praetorium" (q.v.), the judgment-hall (John 18:28; 19:13).
